    What are the arguments both in favor and against this technique when it is applied to security rather than dependability?

    explain 

    Hasan Kahtan · National University of Malaysia

    The terms “dependability”‎ and “security”‎ have been used interchangeably to describe the properties of secure and trusted software.

    However, the extant literature shows that dependability attributes are considered as the cure for security threats, abnormal behavior and untrustworthy issues in a software system.

    A system is considered dependable when it can be depended on to produce the consequences for which it was designed, with no adverse effect in its intended environment. Dependability comprises several attributes that imply availability, confidentiality, integrity, reliability, safety, and maintainability.

    Methods and tools to attain the dependability attributes have been discussed in details in my previous publications.

    I hope this can help you. Good luck.

    Which is the best area in which empirical software engineering can be applied ?

    Dear All,

    What is area in which empirical software engineering be applied? Can be used in evaluating UML diagrams ?

    Zeljko Stojanov · University of Novi Sad

    Dear Nakul,
    empirical methods can be used in any are of software engineering. Choosing the most appropriate method depends on your research goal and research design. You can start with reading some general articles about empirical software engineering, like

    Barbara A. Kitchenham, Shari Lawrence Pfleeger, Lesley M. Pickard, Peter W. Jones, David C. Hoaglin, Khaled El Emam, Jarrett Rosenberg, "Preliminary Guidelines for Empirical Research in Software Engineering," IEEE Transactions on Software Engineering, vol. 28, no. 8, pp. 721-734, Aug. 2002, doi:10.1109/TSE.2002.1027796.

    Timothy C. Lethbridge, Susan Elliott Sim, and Janice Singer. 2005. Studying Software Engineers: Data Collection Techniques for Software Field Studies. Empirical Software Engineering, Volume 10, Issue 3, July 2005, pp. 311-341. DOI: 10.1007/s10664-005-1290-x.

    The best approach is to conduct the research in the area you are the most interested. Read as much as you can about research methods in order to get better insight in available options, and read empirical studies in the most influential software engineering journals to see how other conduct and report empirical research.

    Good luck.

  • Birol Aygün added an answer:
    What is the most commonly used standard for software engineering life cycle ?

    And is there a popular standard for testing and maintenance specifically.  

    Birol Aygün · Yeditepe University

    It would be good education for the questioner if he downloaded the (300+page) Swebok 3 tome and browsed through it.  He would find a lot of potentially useful information, but not the answer to his specific question. Further, there is nothing in Swebok invalidating my recommendation under the conditions I specified.

  • Hanan Aqilan added an answer:
    Do you know any papers on verification of dependency injection modules/IOC containers?

    Dependency injection (DI) is a great pattern/principle to make code better configurable and testable. 

    Using a framework (in Java) such as Guice (or any other JSR 330 implementation), or some other so called "inversion of control (IOC) container", really simplifies using DI. But even the most simple usages are often problematic. E.g. (with an JSR330 annotation with field injection):

    class C {  @Inject X x; }

    This class must not be created via new in normal client code, because then x cannot be injected. Also, assuming X is an interface, there needs to be a configuration (binding) for X.

    I'm wondering if there exist any work on verifying these kind of situations. Are there any IDEs or tools implementing such verification (e.g., creating at least a warning if, given the example above, C is created via new or if no binding for X is detected)? Of course there are many more problems, such as DI cycles etc. 

    Do yo know any research addressing these and other issues?

    So far, I have only found a single paper [HH13], but this paper only scratches the surface. It defines two constraints which are to be satisfied: Compatibility (a binding T to an injected type D must be a subtype: T<:D) and completeness (for all D: exists binding T). Unfortunately, the paper does not handle cases such as scoping, multiple modules etc. And even the simple case of new constructor call as shown in the example is not handled.

  • Rupert Schlick added an answer:
    How can I measure coverage by fault injection?

    In software testing, fault injection is a technique for improving the coverage of a test by introducing faults to test code paths, in particular error handling code paths, that might otherwise rarely be followed.

    let's take this scenario:

    I inject '25' faults in the code and implement two techniques(A, B). suppose 'A' discovers 10 faults and 'B' discovers 15 faults. So as a result B technique is better than A or coverage area of B is better than A.

    So is there any mathematical term to find the coverage? Or how to define it in a formal way? 

    Can i calculate like this,

    coverage of A is (10/25)*100 = 40%

    coverage of B is (15/25)*100 = 60%

    As a result, difference between coverage area of B over A is 20%.

    Rupert Schlick · AIT Austrian Institute of Technology

    Dear Muhammad,

    it is not fully clear to me if what you have in mind is related to mutation testing, as Stefan mentioned, or if you are actually trying to test fault handling mechanisms (like storing information redundantly in two places, to recognize bit-flips in memory - which is not easily done without changing the code itself to emulate those faults).

    Independent of that, if you want to compare test design methods, achieving a high coverage (by whatever coverage metric ever), you will always want to look at what is the "shared" coverage between two methods. So if the 10 "items" covered by your Method A are included in the 15 of your Method B, you could suggest dropping the use of Method A as not gaining anything (B clearly better than A). If none of the covered items of Method A are  included in the ones from Method B, you would apply both methods and gain 100% coverage. In this case none of the single methods is really better than the other.

    And of course, coverage evaluations need to be done on a larger set of systems under test. What works well in one instance might be less than satisfying in the other.

    Best

  • Muhammad Iqbal Hossain added an answer:
    How do I measure FAN-OUT/FAN-IN?

    Fan-in is a measure of the number of functions or methods that call some other function or method (say X). Fan-out is the number of functions that are called by function X. It is used as a call graph based metrics. My question is how to measure fan-in/out from a call graph and where we can use this metrics?

    A sample call graph is given as follows.

    Thanks Maya Daneva for your reply.
    I am trying to calculate fan in-out to measure dependency between functions. I am wondering if it is possible to evaluate my testing technique with this.

  • Maya Daneva added an answer:
    How can I measure size of software system by number of functions?

    In Procedural Programming structure a problem is divided into smaller sub-problems or sub-procedures which can be called as function. A software can be small, medium, large, extra large, ultra large etc. Is there any standard to measure the size of a system by number of functions? Can anyone give me some reference of surveys on it? For example 5-10 function(small), 10-50 functions(medium), 200+ function(extra large).

    What are the known issues for CAN Bus development with Infineon Dave3 for the XMC 4000 series?

    We are currently developing a 1Mbit CAN Bus Interface with the XMC 4500 chips for analog and digital car related sensors (RPM, Gyroscope, Pedals, Temperature). What are the known issues that have come up during the development of similar systems that one should be aware of and prepare for in advance?

    Stanimir Kabaivanov · Plovdiv University "Paisii Hilendarski"

    Well, honestly it is not that easy to provide a definite answer. I can try to answer it based on my experience but with the remark that this answer is still a kind of "speculative" :) one.

    In general to keep up the "responsiveness" of the bus and the nodes one should not have more than 30% bus load. If you go to 60-70% then you risk on loosing data (but of course this all depends a bit on the nodes too).

    I would recommend to use a calculator, like the one here:

  • Paul Anthony Dennis added an answer:
    How can I calculate intraclass correlations for a hierarchical data with binary outcomes?

    My modeled process has binary outcomes and site and region grouping. I am modeling it with a generalized linear mixed model (using GLIMMIX) and a diagonalized covariance structure. Typically I see covariance component based formulas for ICC calculation in the literature. GLIMMIX gives me the covariance of the site indicator and the region indicator variables but not the error variance I need to fill out the formulas. I have seen a suggestion to use 3.29 (pi**2/3) as the error variance when the dispersion is near 1.0, but am not sure this is right.

    Paul Anthony Dennis · Durham VA Medical Center, Durham, United States

    Instead of using a 'random intercept' statement, try modeling the R-side residuals with 'random _residual_'. This option can be used if dispersion is not equal to 1. Here's the support documentation: http://support.sas.com/documentation/cdl/en/statug/63033/HTML/default/viewer.htm#statug_glimmix_sect009.htm

    Hope that helps!

  • Wishnu Prasetya added an answer:
    How can I create state model representation in Model based testing?

    Model based testing is a derivative of Unified Modeling Language (UML) concepts. Usually state machine diagram, interaction diagram etc are used to represent the behavior of system. ATM, Elevator, Vending machines are popular examples for deriving these diagrams. I think these examples are easy to represent in UML diagrams because they contain states and transition. What about other examples which doesn't have explicit state or transition? Like triangle program, sorting problem or search program etc. How can I represent them with state machine?

    Wishnu Prasetya · Universiteit Utrecht

    Well, the Triangle program, or a sorting program, behave more like mathematical functions.  These things do not have a concept of state; so a state machine is not a sensical way to model their behavior. Indeed, they may have internal state (e.g. the value of some local variables at some point in their statement), but their progress from one internal state to another is not something you can control from its interface; to point out that a state machine is not an appropriate way to drive their testing. 

  • Guido Governatori added an answer:
    Are there catalogs with examples of commonsense inference (plausible inference)?

    I am interested in assessing how well certain probabilistic logic languages such as Problog2 implement plausible reasoning, an example of which is "explaining away".

    There are only a few references within AI/Math (see below) which describe patterns of plausible reasoning which are part of human commonsense. My interest is specifically causal plausible (plausal?) inference.

    Are you aware of any philosophy or psychology scholars that I might consult to find references within those domains? Ideally I want extensive catalogs of commonsense reasoning patterns, or plausible reasoning patterns, with examples.

    Any advice on designing a graphical diagram system to develop accounting software?

    in this i mainly targeting on identify drag and drop components to the interface creation and getting use of oop cocept and use of design pattern go to the gui and auto generating part so that still.i haven,t no idea i can climb this mountain.show me a path?in this accounting mean that programme out the reports that need for accounting stuffs.so i want to create a tool that help to people that haven't knowledge about programming language.so they never touch on the language part .help me to enter this topic.is it ok with go though database or gui.

    Juha-pekka Tolvanen · MetaCase

    If your interest is to specify - as far as I understood – GUI elements then most likely domain-specific languages like IFML will do the job. Your users woudl then model with ’sceen’, ’button’, ’navigation’ concepts and not programming concepts like classes, inheritance etc of UML.

    If you interest is to go beyind GUI and addess also business logic of accounting and ask users to specify them I woudl then provide a domain-specific language for them. That language would most likely model ’data’, ’transction’, or be even specific for accounting including ’banking day’ etc. as language constructs.

    A number of years ago I co-authored a related paper: Though it is not (strictly speaking) about a choice-aid for metrics, it is (more generally) about a choice-aid for software development workflow models --- whereby, obviously, the choice of metrics cannot be made independently from the workflow models into which all possible metrics are somehow 'embedded'.
